Ms Kalliopi Mantzavinou

Licensed Psychologist

I am a licensed psychologist, psycho-oncologist, clinical neuropsychologist and certified rehabilitation counselor (CRC), accredited by the US Commission, with professional experience in Greece, Luxembourg and US, specialized in helping people with disabilities, neurological disorders and mental health issues.

About Me

I support individuals navigating the complexities of disabilities, neurological disorders, and mental health issues. My unique background as a psychologist, neuropsychologist, and rehabilitation counsellor offers a truly integrated understanding of your experience. We can work together to explore your challenges and develop practical strategies for everyday life. Clients find this comprehensive approach helps them adapt, build resilience, and enhance their overall well-being.

Approach

Assessment and practical planning shape how therapy unfolds, translating understanding into manageable steps that fit your daily life. Sessions in Hesperange or online (English, French, Greek or Spanish) move at a steady, collaborative pace: focused cognitive work, emotion regulation practice, and problem‑solving tailored to neurological or chronic health challenges. Between meetings I suggest brief, doable exercises and check‑ins to reinforce skills and track progress. Those coping with complex transitions or ongoing medical concerns often find this structured, practical rhythm helpful.
